A usable estimate names the component that failed, the pump setting depth, and the tank pre-charge measured against cut-in. With those three, two quotes can be compared. Without them, a $1,500 total and a $2,500 total may be different jobs.
Depth is the one that moves the number most, and it is the one most often left out. The surcharge runs $500 to $1,000 per additional 100 ft because pipe, wire and hoist time all scale together, so an estimate written without a depth is an estimate that can be revised once the truck is on site. A quote naming 180 ft has committed to something checkable. Fayetteville Well Pump Repair puts it in writing for that reason.
The component matters because it is the difference between categories of work. An estimate reading well system repair against one number is a total, not a diagnosis. Naming the part, the brand fitted and its installed price is what lets a second opinion start from the same place rather than from scratch, and it is what tells you whether the cheap half of the fault tree was ever tested. A pump that will not work covers those tests.
The pre-charge is the one nobody asks for and the one that predicts the future. A flat tank has been cycling the pump, and cycling is what ends motors here. An estimate for a pump on a cycling system that does not state what the tank measured is quoting a replacement into the condition that killed the last one. Pressure tank replacement covers that side.
One line that should not appear: a permit fee on pump work. The county health department issues permits for new well construction rather than for repairs, so a permit charge on a replacement is a charge for a filing nobody makes.

Why does the setting depth matter on a quote?
$500 to $1,000 per additional 100 ft is the surcharge, so depth is usually the largest variable in the total. An estimate without it has left that variable open.
Should a pump estimate include a permit fee?
No. Permits apply to new well construction, not to repairs or replacements, so a permit line on pump work is a charge for paperwork that will never be filed.
How do I compare two very different quotes?
Ask both for the component, the setting depth and the tank pre-charge. Two totals are not comparable, but three matching numbers make the difference between them legible.
